Litter Size

How many babies does a Plains rat have at once? (litter size)

How many baby Plains rats are in a litter?

A Plains rat (Pseudomys australis) usually gives birth to around 3 babies.

Each of those little ones spend around 31 days as a fetus before they are released into the wild. Upon birth, they weight 4 grams (0.01 lbs) and measure 3.3 cm (0′ 2″). They are a member of the Muridae family (genus: Pseudomys). An adult Plains rat grows up to a size of 12.1 cm (0′ 5″).

To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.

The average litter size of a Plains rat is 3

The plains rat (Pseudomys australis), also known as the plains mouse, is a conilurine rodent native to arid and semi-arid Australia. Referred to as the pallyoora or yarlie by Indigenous groups, the plains rat was once widely distributed across central Australia, including north-west New South Wales and south-west Queensland; however, habitat degradation due to grazing, introduced predators and drought have contributed to its decline. Consequently, the plains rat has been listed as ‘presumed extinct’ in New South Wales and Victoria, ‘endangered’ in the Northern Territory and Queensland and ‘vulnerable’ in Western Australia and South Australia. While recent research has indicated the presence of the plains rat in areas such as the Fowlers Gap and Strzelecki Desert regions of New South Wales and within the Diamantina National Park in Queensland, there are only five sub-populations currently recognised nationally, none of which coincide with recent discoveries of the plains rat. As the current population trend of the plains rat has been listed as ‘declining’ by the International Union for the Conservation of Nature (IUCN), the IUCN conservation status for the species is ‘vulnerable’.
